I have Virtualbox 5.0 installed in Mac OS. I installed ubuntu 10.04 as a guest in Virtualbox. I have an external hard drive formated in HFS (I disable journaling), but everytime I tried to plug this HD, Virtualbox tells me :

Failed to create a proxy device for the USB device. (Error: VERR_PDM_NO_USB_PORTS).

Code d'erreur : NS_ERROR_FAILURE (0x80004005)

Composant : ConsoleWrap

Interface : IConsole {872da645-4a9b-1727-bee2-5585105b9eed}

I tried

sudo apt-get install hfsprogs

sudo mount -t hfsplus -o force,rw /dev/sdx# /media/mntpoint

and

sudo fsck.hfsplus /dev/sdx#

Still, the HD doesn't want to mount and Virtualbox gives me the same answer.

Extension pack is installed, device is not blocked by the host. But my device is USB 3.0 flash drive which is connected to USB 3 host port. If I choose USB 3 controller in VM it works fine, but for USB 2 or USB 1 I got above error. If I switch USB 3 drive to USB 2 drive on the same USB 3 port, if don't have the error.
